Objective: Patients with heart failure may experience thirst distress. There is, however, no measurement tool to define patients’ thirst distress in Turkey. The study aimed to determine psychometric properties of the translated Turkish version of the Thirst Distress Scale-Heart Failure (TDS-HF) in a sample of heart failure patients. Design: This methodologically planned study was conducted in two different training and research hospitals in Istanbul. Content validity, confirmatory factor analysis and concurrent validity were used in the validity analysis following the language validity analysis. Reliability coefficients were analysed by calculating Cronbach’s alpha, McDonald’s Omega and test-retest reliability coefficients. Validity and reliability analysis involved 116 patients, and test-retest analysis was carried out among 36 patients who volunteered to participate in the study. Results: The patients had a mean age of 55.2 ± 14.9. The factor structure and the examined fit indices of the one-dimensional eight-item scale indicated that the Turkish version of the scale was consistent with the original model. Item-total correlations were between 0.84 and 0.93, Cronbach’s alpha coefficient was 0.90, the test-retest reliability coefficient was 0.97 and the McDonald’s omega coefficient was 0.93, demonstrating that the scale is highly reliable. Conclusion: The Turkish version of the Thirst Distress Scale-Heart Failure was found to be valid and reliable.

目的：心力衰竭患者可能会感到口渴。然而，土耳其没有测量工具来定义患者的口渴困扰。该研究旨在确定心力衰竭患者样本中土耳其语翻译版口渴困扰量表-心力衰竭（TDS-HF）的心理测量特性。设计：这项在方法上计划的研究是在伊斯坦布尔的两家不同的培训和研究医院进行的。语言效度分析后，采用内容效度、验证性因素分析和同时效度进行效度分析。通过计算 Cronbach's alpha、McDonald's Omega 和重测信度系数来分析信度系数。效度和信度分析涉及 116 名患者，并对 36 名自愿参与该研究的患者进行了重测分析。结果：患者的平均年龄为 55.2 ± 14.9 岁。一维八项量表的因子结构和检验的拟合指数表明，土耳其版本的量表与原始模型一致。项目总相关系数在0.84~0.93之间，Cronbach's alpha系数为0.90，重测信度系数为0.97，McDonald’s omega系数为0.93，表明该量表具有较高的信度。结论：土耳其版本的口渴困扰量表-心力衰竭被证明是有效且可靠的。
